Hi Patrick,
I live about 190 km from you in Courtenay.
Wearing any metal acts as an antenna, increasing the effect, according to some electrical PPL I have listened to. The only real solution would be ridiculous which would be a Faraday cage.
wifi is a transmitter and all transmitters put out rf or whatever you want to call emf etc. A microwave oven does the same thing... causing moisture to react by heating up and cooking. It is one thing to cook food, but when I get near any sort of... especially older wifi transmitters and cellphones, the RF does a job on me. Essentially the heat produced starts breaking down tissue and thus the headache. I speculate that most PPL just don't realize what is happening and just attribute it to a bad hair day.
My speculation is that after approximately 17,000 hours as a pro pilot in a high level IFR environment wearing a noise cancelling headset, I have been somehow sensitized.
One of the first things any pro pilot learns is that it is bad karma to leave the radar transmitter on when on the ground. The newer aircraft generally have a squat switch in the landing gear to automatically de-energize the radar to ensure this. We had it in our 'Runway pre-takeoff checklist' and 'pre-landing CL'.
The reason for this is that during WW2 when radar was first used, the ground crews who guided aircraft in for parking, noticed that when they were in front of or close to the radar transmitter, they felt a lot of heat, especially in the groin or soft tissue areas like the brain, eyes etc. Essentially the concern of becoming sterile was real, as their testicles would cook. This to me is at very minimum, a partial explanation of why sperm counts and testosterone levels in men has plummeted in recent years, because guys putting cellphones in the pant pockets. Believe me, you (male or female as women also have testosterone and need it for their health, mental and physical) do not want your testosterone levels to go down. It is devastating to both women and men.

Also women have gotten cancer in their breasts when they got into the habit of stuffing their cellphones in their bra. The breasts are made of very soft tissue, which of course is easily damaged by RF. There is also cases of PPL like real estate PPL who use cellphones constantly, developing brain tumors around their ears/brain tissue.

There is a book called Dirty Electricity by epidemiologist Dr Sam Milham that describes some cases of schools being afflicted by cell towers and in some countries they are not allowed to be anywhere near schools because children's bodies (and the elderly and women) have much more delicate tissue than adults.

This is real and well known and documented. The certification for instance for cellphones included using a skull of a US Marine to measure the RF/heating of the brain from cellphones. Since US Marines (or at least all of the ones I have seen) tend to be typically 6 foot plus and very strong and well developed physically their skulls * will tend to be thicker and so thus less effect. This is a problem because small children and women whose skulls are substantially thinner allow substantially more RF to heat up the brain causing damage.
Take a look in you iPhone handbook at the warning that says the cellphone should be a minimum of (I believe) 5/8 of an inch from your ear. How many PPL actually know that or have a clue why???
* I read the report of an anthropologist who was describing an ancient battlefield where one of the armies' men shaved their heads. The anthropologist could tell which army the skull that was unearthed belong to, because the ones that shaved their heads had thicker skulls, because when you shave your head the sun causes more vitamin D to be produced and thus more bone is created locally and thus a thicker skulls. US Marines are required to remove most of their hair and thus have thicker skulls.
